Simonsen Metal Film Box

This is a very old metal film box, made in Chicago, Ill. USA by The Simonsen Metal Products Co.
It was originally made to store film movies, but I am not sure if they are 8mm or 16mm or another size. The Metal box has a sturdy metal handle to carry the box and all its weight around. Inside it has space to hold 6 reels of films. on the inside of the lid it still keeps the card with numbers to write the name of each of the films stored.
The metal box measures 5" tall by 5 1/2" deep and 4 1/4" wide. On the front of the lid it keeps, in great condition the label of the manufacturer, It has a Spaniel Dog picture and it reads: " Simonsen Metal Products, Co. Trade Niki Mark, Trickle Tool Bond-Film, Boxes of Quality, Chicago, Ill. USA"
No rust, no damage, Excellent condition!
